Answers

Answer:

m∠y = 50 (Due to A)

m∠x = 50 (Due to F)

Step-by-step explanation:

Due to corresponding angles,

x = y = 50

Also, another thing... You wrote 60 degrees as your answer for the first part, you did a slight miscalculation.

180 - 130 = 50

So the answer for the first part is 50 degrees. However, the reasoning is correct!

Solve the simultaneous equations
5x - 4y = 19
x + 2y = 8

Answers

Answer:

x= 5 and y = 1.5

Step-by-step explanation:

5x -4y = 19

x + 2y = 8

let x = 8 - 2y...

5x - 4y = 19.......x = 8 -2y

5(8-2y) - 4y = 19

40 - 10y -4y= 19

40-14y = 19

-14y = 19-40

-14y = -21

y = 1.5

x = 8 - 2(1.5)

x = 8 - 3

x = 5

Thus, x is 5 and y is 1.5

Hope this helps!!!!

[12(x+3)-4]-2(x-1)+6]

Answers

10(x + 4)

Step-by-step explanation:

Simplify :

[12(x + 3) - 4] - 2(x - 1) + 6

= [12x + 36 - 4] - 2x + 2 + 6

= 12x - 2x + 36 - 4 + 2 + 6

= 10x + 32 + 8

= 10x + 40

= 10(x + 4)

b. −81


c. 81


d. 108

Answers

Answer:

1. d  2. a  3. d  4. a  5. a

Step-by-step explanation:

For 1, d is negative because, if there an even number of negatives, the answer will be positive. a. would have been correct, but you multiply that one by 0. 0 is not negative, so the answer has to be d.

2. is -21. You can multiply 3 times seven then make it negative, or simply add -7 together 3 times.

3. is d because the two negatives cancel each other out. Even numbers of negatives cancel each other out. therefore, 17 times 6 is 102.

4. -120 is the answer because there are 3 negatives. That is an odd number, so we know our answer is negative. -5 times -3 is 15, and 15 times -8 is -120.

5. is a because -1 times 4 is -4, then -4 times -9 is 36. 36 times -3 is then -108.
